Tokyo Cabinet is a library of routines for managing a database. The database
is a simple data file containing records, each is a pair of a key and a
value. Every key and value is serial bytes with variable length. Both binary
data and character string can be used as a key and a value. There is neither
concept of data tables nor data types. Records are organized in hash table, B+
tree, or fixed-length array.
Tokyo Cabinet is developed as the successor of GDBM and QDBM on the following
purposes. They are achieved and Tokyo Cabinet replaces conventional DBM
* improves space efficiency: smaller size of database file.
* improves time efficiency: faster processing speed.
* improves parallelism: higher performance in multi-thread environment.
* improves usability: simplified API.
* improves robustness: database file is not corrupted even under catastrophic
* supports 64-bit architecture: enormous memory space and database file are
